Francisco completed 15 math questions in 4 minutes. If he completed each question in the same amount of time, how many seconds did he spend on each question?

Answer 1

Ooh, this one's a little bit trickier! We're going to need to do some unit conversions to solve this one. Let's start by figuring out how many seconds are in 4 minutes. There are 60 seconds in a minute, so 4 minutes is equal to 4*60 = 240 seconds. Now that we have that information, we can set up a proportion to solve for the number of seconds per question. So, we have: t/15 = 240/4. we can cross-multiply to solve for t, the number of seconds per question. So, we get: t*4 = 15*240. Simplifying this gives us: t = 600 seconds. So Francisco spent 600 seconds on each math question. Does that make sense ?
